[Elecraft] K3 and Android

[Richard Fjeld]

Sorry, my answer is not specific to the K3 like you asked.

I don't know if you have looked through your Google Play Store which is most likely on your Galaxy.  There are a ton of apps to be had.  

I found a '555 calculator' that will give the R and C values to connect to a 555 chip for desired timing. Also, an excellent scientific calculator, a Ohm's law/Watt's law calculator, and a GPS app.  They were all free.
